5 Insights: How Does Cloud Figure into Enterprise IT Sourcing Plans? Provider Site: 52.9% Customer Site: 47.1% [Q3] Please estimate what percentage of your organization s total annual IT budget is allocated to each of the following procurement/management models. Traditional Outsourced (eg., Application Management) 21.5% Today External Cloud: 31.4% Virtual Private Cloud 5.5% Traditional In-house 36.4% Public Cloud 19.5% Dedicated Private Cloud 6.5% In-house Private Cloud 10.7% Traditional Outsourced (eg., Application Management) 21.5% In 24 Months External Cloud: 40.8% (29.8% growth) Virtual Private Cloud 10.8% Dedicated Private Cloud 12.0% Traditional In-house 27.5% Public Cloud 17.9% In-house Private Cloud 15.7% Provider Site: 56.8% (7.5% growth) Customer Site: 43.2 Public cloud is transformative and challenges all our notions about how IT is bought, staffed, operated, and capitalized Private cloud is evolutionary for the vast majority of enterprises, and the likely onramp to cloud for the next 24 months Hybrid approaches to IT delivery are already a standard, but cross-platform management is the next frontier Source: IDC CloudView Survey 2014, n=2378 worldwide IT respondents 5

6 Cloud: A Strategic/Key Resource For Nearly 80% of Respondents Q. Which of the following best describes your organization's view of cloud computing/iaas? A strategic part of our IT environment moving forward 45% Another IT resource that we will use as part of our portfoli 35% We will take a wait and see approach on how best to use clou 18% We don't understand how cloud computing/iaas could be used b 2% 0% 10% 20% 30% 40% 50% N=504 Base: currently use OR plan to use cloud computing for IT infrastructure Source: 2014 IDC U.S. Enterprise Communications Survey IDC Visit us at IDC.com and follow us on 6

7 Rise of Software-Defined Networking Software Defined Networking (SDN) is emerging as a new architectural approach to networking in the cloud era Establishes clear abstractions for automation and programmability, and orchestration, resulting in business and operational agility. Integrates well with major cloud platforms Can drive OPEX savings in large data centers through automated network provisioning, configuration Potential to reduce CAPEX expenditures by allowing for purchase of industry-standard hardware (x86 for NFV, switches) IDC Visit us at IDC.com and follow us on 7

8 What s Driving Today s SDN Deployments? Q. Which of the following factors is the primary motivation for considering or implementing SDN? Need the network to have more agility to support virtualization applications/cloud 29 Increase ability to deliver new applications or services across the network 23 Require better programmability of network for operational efficiency (OpEx gains) 21 Increase speed of provisioning the infrastructure for application workloads 12 Scale the network to support various and growing workloads 8 Simplify moves, adds, changes and decommissions Use SDN to lower CAPEX (initial investment costs) % 5% 10% 15% 20% 25% 30% N=228 Source: IDC's 2014 SDN Survey, April 2014 IDC Visit us at IDC.com and follow us on 8

13 Essential Guidance Workloads are driving new requirements across the entire spectrum of IT Infrastructure radiating out from the datacenter to the WAN and branch Take an application-centric view of IT Infrastructure to see how workloads are processed and delivered, and look to automate where possible. Datacenter is where the greatest pain was felt, so that s where SDN disruption hit first, but WAN and branch also benefit from of abstraction, automation, policy enforcement, virtualization, and orchestration Mitigating MPLS backhaul for cloud -- using Internet broadband and cloud VPNs wherever possible -- is a major business driver Dare we call it the Software-Defined WAN (SDW)? Whatever we call it, there s a definitely need WAN technologies and services are ripe for disruption IDC Visit us at IDC.com and follow us on 13
